Title: Process for the production of block copolymer of propylene
Inventor: FUJIO ICHIRO
IPC: C08F2/00
Filed: 1987-01-13
Granted: 1991-12-31
Abstract: ABSTRACT    A block copolymer of propylene can be obtained with its quality controlled uniform by conducting at first continuous polymerization of propylene in a polymerization system, receiving a polymer slurry, which has been discharged continuously from the polymerization system, in a batchwise polymerization tank, feeding ethylene to the tank to conduct batchwise polymerization of ethylene and propylene.  Upon discharge of a copolymer slurry formed by the preceding batchwise polymerization, at least a predetermined amount of unreacted ethylene is left over in the tank.  Into the tank with the unreacted ethylene still left over wherein, there are simultaneously charged the polymer slurry from the polymerization system and a deactivator. During this charging, ethylene is not supplied.  The charging rate of the deactivator is controlled in such a way that the partial pressure of ethylene in the vapor phase of the tank always reaches a predetermined valve at the time point of completion of reception of the polymer slurry therein.  The method of the instant invention produces a propylene block copolymer of uniform quality as compared with batchwise polymerization techniques in which difficulties are encountered in maintaining the quality of the resulting propylene block copolymers uniform.

Title: Process for separation of acid gases
Inventor: KADONO YUKIO
IPC: C10K1/16
Filed: 1987-05-06
Granted: 1992-01-07
Abstract: ABSTRACT OF THE DISCLOSURE Diisopropyl ethers of oligomers of ethylene glycol having between 2 and 8 ethylene glycol moieties and an average molecular weight between 190 and 300, are more useful physical absorption solvents for the separation of acid gases than are dimethyl, diethyl, ethyl butyl, propyl butyl, dibutyl, or higher alkyl ethers of the same ethylene glycol oligomers, because of a combination of high solution capacity, high separation efficiencies, low viscosity, low gas pressure, and resistance to hydrolysis during use.  The diisopropyl ether of diethylene glycol is especially advantageous for use at absorber temperatures below 0°c.  Because of low viscosity, the diisopropyl ethers can often be substituted in separation equipment designed for use with chemical rather than physical solvents, thereby realizing the lower operating costs associated with physical solvents without requiring new capital investment.

Abstract: ABSTRACT OF THE DISCLOSURE An automatic cooking control system for a microwave oven comprising an initial operation process which comprises of shifting a temperature of inflow air stored in memories to other memories and storing repeatedly an inflow air temperature detected at present to another memory until the present detected inflow air temperature is equal to the temperature stored in the memory, seeking a temperature variation of inflow air and a temperature difference between the inflow and outflow airs, obtaining a temperature compensating portion from the temperature variation and difference, and establishing a temperature increment by dividing the temperature compensating portion from a predetermined temperature increment.  A first stage heating process operates until the temperature of exit air from a heating chamber is raised as much as the compensated temperature increment.  In a second stage heating process is carried out for the time of the first stage heating time multiplied by a predetermined value according to the kind of food.  Thereby, it is possible to establish quickly the temperature increment and to improve the reliability of automatic cooking.
